Haringey Council confirmed it would be closing the gates from 10pm to try to avoid a repeat of last Wednesday night’s illegal rave, which spilled from the streets into the park.

The council, which cannot close the gates earlier as groups and organised activities use it in the evening, said it will continue to “work with the police to review safety measures in this area”.

Cllr Paul Convery, Islington Council’s executive member for community safety, welcomed the decision. “A lot of things happen in Finsbury Park late at night which are unpleasant, so closing the gates might not be a bad solution,” he said.

“It’s frustrating for us as almost exactly a year earlier a similar thing happened around GCSE results.

“It was put out on social media, and some pretty evil natured people decided to go along and sell drugs and stir up trouble.

“People need to learn that they can’t advertise this sort of thing on social media.”

Last week’s incident saw hundreds of revellers congregate for a party late on Wednesday after it was advertised on Twitter under the hashtag #PreCarnivalBlockParty.

Police were called just after midnight when the illegal rave apparently began to spiral out of control.

A police spokesman said: “Officers, including the Air Support Unit and Territorial Support Group, attended.

“While in the area, officers responded to a fight nearby and a number of items were thrown towards them.

“One officer sustained facial injuries and has been taken to hospital for treatment.”

Forty minutes after the original call, London Ambulance Service called police to nearby Moray Road after a man was found suffering from a stab wound to the leg. He was taken to a central London hospital, and has since been discharged.

Police stayed at the scene until after 3am when the party broke up.

One person was arrested on suspicion of possessing an offensive weapon, and the injured officer – who suffered bruising to his jaw – has been discharged from hospital.
